Specification forming part of Letters Patent No. 131,823, dated October 1, 1.872.

To all 'whom it may concern:

Be itknown that I, HENRY MARTIN, of Dimcan, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Cooking-Range, of which the following is a specication: I

Figure lis a front elevation of my improved cooking-range. Fig. 2 is a vertical longitudinal section of the same on the line c c, Fig. 3.

Fig. 3 is a horizontal section of the same on the line k k, Fig. 2.

Similar letters of reference indicate correspending parts.

This invention relates to a new construction of cooking-range5 and has for its object to reduce the combustion of fuel to the greatest practicable extent without impairing the heating capacity of the range. The invention consists in arranging the lire-place between the oven and boiler, in making the oven removable, and `in the arrangement of a judicious draft-system in connection therewith.l

A, in the drawing, represents the inclosing ease or shell of the range, of suitable size. B

is the fire-place therein; C, the water-boiler; andD, the oven. The nre-place is between boiler and oven, as shown, and radiates its lateral heat to the benefit of both. Under the fire-place is the ash-pit c, and below the same4 the ash-pan b. A part of the products of combustion passes from the {ire-place B beneath the boiler C, and a part around the oven D, and thence the respective currents reach the flue E by the branches d and e. The escape of smoke through either of these branches can be more or less arrested by means of dampers f and g. The damper f is arranged within the case A directly in front of the entrance to the 4branch d, and will, when shut, prevent circulation around the boiler. The damper gis arranged on a horizontal partitiomh, which is stationary in the case A beneath the oven, as

shown in Fig. 2. The oven itself is removable from the shell of the range, and confined therein by pivoted knobs i i, as'shown in Fig. 1. Whenever the interior of the range is to be cleaned the oven is removed and subsequently replaced.

Having thus described my invention, I claim as new and desire to secure by Letters Patl ent- The range, con taining the nre-place between the boiler and removable oven, the smoke-fine E with its branches d e, the dampersfg, and plate h, all arranged substantially as herein shown and described.
